Abstract
Concentrations of beta-endorphin were measured by radioimmunoassay in discrete brain nuclei of young (3 months) and old (24 months) rats. The beta-endorphin content of all major structures known to contain this peptide with the exception of the eminence, is reduced (50.3 +/- 2.8% of control) in old rats.
摘要
通过放射免疫分析法测定了年轻（3个月）和年老（24个月）大鼠离散脑核中β-内啡肽的浓度。除隆起外，已知含有这种肽的所有主要结构中的β-内啡肽含量在老年大鼠中均降低（为对照的50.3±2.8%）。
